The Ideal Ventilation Solution for any Application
Unmatched in quality and performance. Designed for greater cooling capacity
and durability than competitive products, Attic Breeze delivers up to
1550 CFM of cooling performance, more than any residential solar powered
attic fan available.
UltraFlō™ design technology is the proprietary fan design technology developed by Attic Breeze which allows our products to move a maximum amount of airflow for a minimum amount of energy input.
All aluminum rust-free construction.
Wind Turbines Reduce energy bills.
Permanently lubricated upper and lower ball bearings ensure that wind turbines offer long life and no maintenance.
Technically, wind turbines aren't a fixed vent system because they use a moving part to help exhaust air from an attic. That moving part consists of a series of specially shaped vanes that turns wind force into a rotary motion. As the spinning vanes gain velocity, they create an area of low air pressure. That low pressure, in turn, pulls air from an attic.
The best place to install intake vents is in or near the roof eave or soffits. That location provides two key advantages:
1. The vents are better protected from rain and snow infiltration. Vents mounted in the eave provide almost total protection.
2. Usually, when undereave vents are placed on both sides of a roof (as they should be), there's always an equal distribution of high and low pressure areas.
Proper ventilation is key to preventing high attic temperatures from putting too much pressure on the duct system and eventually leaking heat into the home. On this 63 degree March day this under-ventilated attic was 105 degrees already!
This attic was so hot the sap had leeched out of the wood from the roof joists. In this climates attic temperatures can reach 165 degrees.
This is a typical situation we find with most homes in the DFW area. The builders priority is not to ventilate your attic but to pass the final inspection so they can sell the house. In this instance, somebody ran up with a hammer, smashed a hole in the soffit and then stapled a 8"x16" cover to hide what they did. If you check your own house the hole may only cover 30 to 60% of the required space.
Here is another typical situation we find with a small hole hidden by a larger cover. We use a reciprocating saw to widen the hole to the proper size and clean and clear any blockages impeding intake attic ventilation.
Here is a fully open soffit vent with no blockages. The typical home needs at least one this size (8"x16") for every 100 square feet of attic space. Each solar power attic fan needs 12 this size to work properly. Next we would cover the opening with a new grill cover painted to match the exterior color.
Static vents are designed to permit an efficient, unobstructed outflow of attic air. In addition because they're installed high in the attic where there's greater exposure to the weather, these units must be designed to prevent (or at least minimize) rain and snow infiltration. Static Vents must be used with intake vents to provide a balanced system and thus an adequate flow of air through an attic.
What is Ventilation?
Simply the process of supplying a continuous supply of air through the attic space
50% intake/50% exhaust
Exhaust must be at least 3 feet higher than the intake system
Intake should be under eave
Exhaust should be near or at peak
Too Much Of A Bad Thing!
Here is a great example of poor ventilation. There are two static vents on the top row with an old electric power fan that probably doesn’t work in the middle. In order to improve the situation somebody decided to install 3 fourteen inch wind turbines BELOW the existing ventilation. Unfortunately this will not help anything because the wind turbines are placed too low on the north side of the roof and will never spin with the predominately southern trade winds in the spring, summer and fall in Texas. Even as passive ventilation they are too low on the roof where heat will exit at the highest point. Too much ventilation this close together will also cause wind washing where each vent will try and pull air from adjacent vents thus rendering them useless.
